Excel Invoice & Sales Sheet

I have a small window—just two days—to pull my handwritten / PDF records into a clean, reusable Excel file. The file will contain two separate worksheets:

• An invoice template that already has fields for customer details, an item-by-item product list, and clear payment terms. All I should have to do is drop in the numbers and hit print or save to PDF.

• A sales tracker that accepts the same source data (sales figures, customer information, product details) and automatically calculates both total sales and the percentage growth over time. The summation and growth-rate formulas need to be locked in so totals update the moment new rows are added.

I will supply the raw notes and scans; you turn them into a polished workbook ready for daily use. Accuracy of the formulas and a professional, easy-to-read layout are the key acceptance criteria.
